Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: NFSv4.2: fix nfs4_listxattr kernel BUG
 at mm/usercopy.c:102 A call to listxattr() with a buffer size = 0 returns the actual size of the buffer
 needed for a subsequent call. When size > 0, nfs4_listxattr() does not return an error because either
 generic_listxattr() or nfs4_listxattr_nfs4_label() consumes exactly all the bytes then size is 0 when
 calling nfs4_listxattr_nfs4_user() which then triggers the following kernel BUG: [ 99.403778] kernel BUG
 at mm/usercopy.c:102! [ 99.404063] Internal error: Oops - BUG: 00000000f2000800 [#1] SMP [ 99.408463] CPU:

 aa0003e3 d000a3e0 91310000 97f49bdb (d4210000) Issue is reproduced when generic_listxattr() returns
 'system.nfs4_acl', thus calling lisxattr() with size = 16 will trigger the bug. Add check on
 nfs4_listxattr() to return ERANGE error when it is called with size > 0 and the return value is greater
 than size. (CVE-2024-26870)

Solution

Update the sys-kernel/csql-kernel-6_1 library and its related packages to version 18244.85.5 or later.
